Shanghai, China (Sports Network) - Peter Hanson fired an 8-under 64 on Friday to grab a 2-stroke lead after 36 holes at the BMW Masters.
Hanson, who won for the fifth time on the European Tour earlier this year, finished two rounds at 14-under-par 130.
The Swede leads his Ryder Cup teammate, Rory McIlroy, by a pair. McIlroy carded a 65 to move into second place at minus-12 at Lake Malaren Golf Club.
Robert Karlsson also had a 64 to jump into third at 9-under-par 135.
First-round leader Jamie Donaldson stumbled to a 2-over 74. He dipped into a share of fourth at minus-8 with Justin Rose (68), Alexander Noren (68) and Shane Lowry (64).
Hanson and McIlroy helped the Europeans win the Ryder Cup last month and three of their teammates -- Luke Donald (67), Nicolas Colsaerts (68), and Martin Kaymer (69) -- are among eight players tied for eighth at 7-under 137.
Ten players from the winning European Ryder Cup team are in the field, and five of them stand in the top 15 on the leaderboard at the halfway point.
